A technical paper titled “Programmable quantum emitter formation in silicon” was published by researchers at Lawrence Berkeley National Laboratory and University of California Berkeley. Abstract: "Silicon-based quantum emitters are candidates for large-scale qubit integration due to their single-photon emission properties and potential for spin-photon interfaces with long spin coherence t... » read more

Research Bits: June 4
By Jesse Allen - 04 Jun, 2024 - Comments: 0

Ultra-pure silicon Researchers from the University of Manchester and University of Melbourne developed a technique to engineer ultra-pure silicon that could be used in the construction of high-performance qubit devices that extend quantum coherence times. The highly purified silicon chips house and protect the qubits so they can sustain quantum coherence much longer, enabling complex calcul... » read more

Enabling Advanced Devices With Atomic Layer Processes
By Katherine Derbyshire - 18 Apr, 2024 - Comments: 2

Atomic layer deposition (ALD) used to be considered too slow to be of practical use in semiconductor manufacturing, but it has emerged as a critical tool for both transistor and interconnect fabrication at the most advanced nodes. ALD can be speeded up somewhat, but the real shift is the rising value of precise composition and thickness control at the most advanced nodes, which makes the ext... » read more

Technology Advancements For Dynamic Function eXchange In Vivado ML Edition
By Xilinx - 11 Feb, 2022 - Comments: 0

As systems become more complex and designers are asked to do more with less, adaptability is a critical asset. While Xilinx FPGAs and SoCs always provided the flexibility to perform on-site device reprogramming, current constraints including increased cost, tighter board space, and power consumption demand even more efficient design strategies. Xilinx Dynamic Function eXchange (DFX) extends the... » read more

X-ray Imaging of Silicon Die Within Fully Packaged Semiconductor Devices
By Technical Paper Link - 21 Jan, 2022 - Comments: 0

Abstract: "X-ray diffraction imaging (XRDI) (topography) measurements of silicon die warpage within fully packaged commercial quad-flat no-lead devices are described. Using synchrotron radiation, it has been shown that the tilt of the lattice planes in the Analog Devices AD9253 die initially falls, but after 100 °C, it rises again. The twist across the die wafer falls linearly with an incre... » read more

Defect Mitigation And Characterization In Silicon Hardmask Materials
By Brewer Science - 17 Mar, 2021 - Comments: 0

From SPIE Digital Library: In this study, metal contaminants, liquid particle count and on-wafer defects of Si- HMs and filtration removal rates are monitored to determine the effect of filter type, pore size, media morphology, and cleanliness on filtration performance. 5-nm PTFE NTD2 filter having proprietary surface treatment used in this study shows lowest defect count. Authors: Vineet... » read more
